Only slides and green screen

I can record fine I see images from camera but when I review I get audio and slides but all images from camera are green screen.
Thanks for some help.

I'm seeing the same behavior, some F4V files from Capitivate encode/convert fine in ffmpeg, some don't.
This is a strange one. Posted a copy of the source to
http://markusbucket.s3.amazonaws.com/watch_s3_source/5924_doesntwork_eBay_orig.f4v
Tried running plain html5 outputs, Apple Compressor, QuickTime Player 7/X (Mac 10.6.5), Handbrake... all failed to output correctly. The strange thing is that both VideoSpec and MediaInfo seem to report it as a plain ol' h264/aac file.
Please let me know if you've found a workaround, or if Capivate allows export to formats other than just these misbehaving F4Vs.
Thank You,

Camera video preview - Random crashes and green screens

Hello everyone,
I am currently working on a Windows Phone 8.1 app and I need to preview video from the phone's back camera. For quite some time I've been struggling with random crashes and green screens. When these green screens appear, all camera apps become affected and
the device needs to be restarted. Occasionally the phone freezes and only recovers after battery removal. I test the app on my Lumia 620.
After some web search, I found references to the same problem by many users/developers of different apps. I'm really frustrated as I've tried many possible solutions with no avail.
Here is part of my code:
//in App.xaml.cs:
MediaCaptureInitializationSettings settings;
public static MediaCapture captureMgr;
public static bool UnableToInitializeCamera = false;
public async Task InitializeVideoCapture()
DeviceInformation backWebcam = await GetCameraDeviceInfoAsync(Windows.Devices.Enumeration.Panel.Back);
if(captureMgr!=null) captureMgr.Dispose();
captureMgr = new MediaCapture();
settings = new MediaCaptureInitializationSettings();
settings.StreamingCaptureMode = StreamingCaptureMode.Video;
settings.PhotoCaptureSource = PhotoCaptureSource.VideoPreview;
settings.AudioDeviceId = "";
if (backWebcam != null)
settings.VideoDeviceId = backWebcam.Id;
else
var _messageDialog = new MessageDialog("Back panel camera not found");
_messageDialog.Commands.Add(new UICommand("OK"));
_messageDialog.ShowAsync();
try
await captureMgr.InitializeAsync(settings);
captureMgr.SetPreviewRotation(VideoRotation.Clockwise90Degrees);
UnableToInitializeCamera = false;
catch
UnableToInitializeCamera = true;
Debug.WriteLine("HANDLED EXCEPTION: camera could not be initialized");
var _messageDialog = new MessageDialog("Unable to initialize camera");
_messageDialog.Commands.Add(new UICommand("OK"));
_messageDialog.ShowAsync();
protected override async void OnLaunched(LaunchActivatedEventArgs e)
//.... other app initialization code
await InitializeVideoCapture();
Window.Current.Activate();
private async void OnResuming(object sender, object e)
AppIsResuming = true;
FinishedCameraInitialize = false;
await Task.Delay(TimeSpan.FromSeconds(0.5));//this makes crashes less frequent
await InitializeVideoCapture();
FinishedCameraInitialize = true;
if(WasPreviewingCamera)
WasPreviewingCamera = false; //the following line allows time for SetupPage._captureElement to be assigned before video preview starts while (!SetupPage.CaptureElementSourceAssigned) await Task.Delay(TimeSpan.FromMilliseconds(1));
SetupPage.CaptureElementSourceAssigned = false;
try
Debug.WriteLine("trying to restart video preview");
await captureMgr.StartPreviewAsync();
SetupPage.PreviewingCamera = true;
catch
Debug.WriteLine("HANDLED EXCEPTION: unable to start previewing");
SetupPage.PreviewingCamera = false;
GC.Collect();
AppIsResuming = false;
private async void OnSuspending(object sender, SuspendingEventArgs e)
var deferral = e.SuspendingOperation.GetDeferral();
while (AppIsResuming) await Task.Delay(TimeSpan.FromMilliseconds(1));//prevents crash when app is suspended right after it is resumed
await CleanupCaptureResources();
TimeOfLastSuspend = DateTime.Now;
FinishedCameraInitialize = false;
GC.Collect();
deferral.Complete();
public async Task CleanupCaptureResources()
if (SetupPage.PreviewingCamera)
await captureMgr.StopPreviewAsync();
WasPreviewingCamera = true;
SetupPage.PreviewingCamera = false;
else WasPreviewingCamera = false;
if (captureMgr != null) captureMgr.Dispose();
//in SetupPage.xaml.cs
void OnSuspending(object sender, Windows.ApplicationModel.SuspendingEventArgs e)
var deferral = e.SuspendingOperation.GetDeferral();
_captureElement.Source = null;
CaptureElementSourceAssigned = false;
GC.Collect();
deferral.Complete();
private async void OnResuming(object sender, object e)
ProgressRing2.Visibility = Visibility.Visible;
ProgressRing2.IsActive = true;
while (!App.FinishedCameraInitialize) await Task.Delay(TimeSpan.FromMilliseconds(1));
App.FinishedCameraInitialize = false;
captureElement.Source = App.captureMgr;
CaptureElementSourceAssigned = true;
GC.Collect();
ProgressRing2.Visibility = Visibility.Collapsed;
ProgressRing2.IsActive = false;
Any help towards a solution will be greatly appreciated.
Thank you

I will also advice that you start by following the
Windows Store app sample.
Is this a Windows Phone app?
The crash/green screen only manifests itself when I suspend my app and switch to the default camera app (could be any other camera app perhaps). It happens roughly 1 out of 8 times. That's why I posted the suspension and resuming handlers, which I wrote
according to the msdn instructions.
I found
this page with a sample that demonstrates the MediaCapture API for Windows Phone. Some developers have reported problems similar as mine. Has Microsoft dealt with this issue?
I've spent quite a few weeks trying to investigate this problem, without actually knowing if it is my code that needs to be debugged. That's why I'm asking if other developers are facing similar problems.
Thank you
Edit: It seems that the crash/green screen can appear when suspending/switching to any app (regardless if it uses the camera or not). Also, all works fine when the app is running on the debugger.

Black and green screen after water

Well I did this huge accident by dropping my iPhone 5 into the toilet, but it was only in there for 2sec. I dried the phone and it was still working, but after a while it turned itself off. As a reaction, I hurried starting it again to check if it still was working and it was. But after that, my friend told me to turn the phone off again as soon as possible.
When I got home, I placed the iphone in a bag of rice without any air in it, and waited over 24 hours to check it.
When I checked it(which I think I did too early)- it worked, and I was so happy! Everything, the sound was just fine, but after a while it didn't respond to my touches and suddenly the screen became black and green pixle-ish and grumsy, but I could still see something in the background.
I placed it back into the rice, but this time on my bathroom floor in a bag, because it's warmer there.
I don't dare take it out before I know that most of the water is gone, but at the same time I don't know what the problem with the screen was. Is it possible to fix it? I think I maybe can get some help from a friend, but it would be nice if anyone knew what i could do, or what the problem is.
I also read about people who got problem with black and green screen on their iPads. Everyone who read the thread had hit their iPads on the backside of the iPad and it got normal screen again.

Thanks, I will try that after a couple of days. I want to make sure that my iPhone is completely dry inside.
Anyone who knows how long it may take for an iPhone to dry inside after 2-3sec in water? Its in a bag of rice.

Blue and Green Screen

Can you do blue screen and green screen things on Final Cut Pro? Don't tell me how because I don't own it. I just want to know if it's possible.

Look at DV Matte Pro...as another option.

Scaling and green screen in premiere cs5.5

Some background.
Years ago we used visual communicator pro to do some green screen shooting. I frankly did not know what I was doing with the lighting, and got a lot of spill and shadow. I've been looking for a way to fix this. I recently bought cs5.5 to be able to do this with Ultra keyer.
I also have VC 2.0 running on the same computer.
Since I don't want to set the background, and since Pr does not know how to import visual communicator raw camera streams (please, does anyone know how to convert these into something that pr can handle) , I decided on this course of action.
I rendered the vidieos in VC using a synthetic green screen (basiclly a solid green image produced in painshop with a color fill).
I have rendered videos with this, and they have a solid green background with a lot of shadows in .avi format.
I have a background that was originally to be used with each clip. The backgrounds are smaller than the dvi resolution of the rendered videos, so need to be scaled. They may eventually be replaced, but not right now. I am trying to get these rendered into green screens. i've watched a half dozen youtube videos and have gotten part way.
What I have done is:
Imported this image into pr as track 1 and the video as track 2. stretched the image length to match the video track.
I have dragged the garbage matt onto the video. I have dragged ultra keyer onto the video. I can play the green screen video.
I need to scale the image. I've tried everything in all the adobe help files and nothing seems to work. Clicking on the transform icon and twirling the scaling open, I cannot get the handles to appear around the image in the monitor window, no matter what I try. If I change to the video window and twirl open ultra key and 8 point garbage map, and click on the transform button, the handles for the garbage matt do not appear. If I click on the eyedropper, I can select the key color, but it doesn't take effect.
I am sure this is pilot error,
What am I doing wrong?

I have it working. The panel is the timeline. In the effects menu you can click the double arrow and the timeline view opens up. THEN it works. Go figure.
At this point I was able to render a video. But even with a lot of tweaking of choke, alpha channel etc, I have not been able to get rid of the gray border around the figure. It is there in the original rendering from VC and I was hoping to be able to get rid of it. So far no joy. I did try using it as the key, but that got othe grays in the hair, so that is no good. I wish where was sort of a spline garbage map that you could use to tighly outline a figure, and then the renderer would be able to track motion and keep the spline garbage map with the figure outline. It would take a lot of computing but theoretically it could be done. Or even an auto-trace feature like the one in the old corel draw, which would autotrace an image, making a vector spline out of it. It would then be possible to create a mask that would follow the motion of the actor.
The shadows and such are cleanly gone though. So now if I can reproduce the ability to do this on another clip, I have a fighting chance. It is sad that Adobe has abandoned VC pro. The teleprompter was a nice feature.
I imagine that I can simulate one using some other adobe tool, but I'll just have to play with it. I can see that using a good digital camera on a green screen and shooting footage that way will be a better solution. The only problem is that in the past 6 years since the footage was shot, my wife has aged a bit, so reshooting these shots and trying to combine the good ones with the bad ones, might not be as cohesive as one would like.
I appreciate your time. I still don't know exactly *what* I did that made it start working, but I am pretty sure it was opening the timeline in the effects window.

Videos randomly only show blank green screen

I have a Dell computer with Windows 7. I am using my iphone 4s to capture videos and then edit them in Adobe Premiere Elements 12.
What seems to be at random, I insert a video and only the audio works. Instead of seeing my video footage, I see a blank green screen.
I have tried to move that video around and changing applied effects to see if that will somehow restore the video. I have tried Smart Fix but that did nothing as well. I deleted the video from the program and tried to drop the file again but it still showed a blank green screen. I tried restarting the program but that did not change anything. I even tried uploading the video from my phone to my computer all over again but that did not change anything.
If I play the video on my computer through Quick Time Player or Windows Media Player (NOT with the Adobe PE 12 program) it plays fine. I play it on my phone and there are no problems either. The only problem is that randomly there are videos that will show a blank green screen in the program. What can I do to fix this?
I would genuinely appreciate any help offered!

Do you find that these random videos with problems were shot with varying low lighting conditions?
The best I can tell you are probably shooting 1080p30 with your iPhone 4S.
Trying taking this problem video into the free HandBrake program and converting it to 1920 x 1080
at 30 frames per second, making sure that the frame rate setting is for Constant and not variable frame rate.
The codec set should be H.264.
http://handbrake.fr/
If you need any help with setting the program up, please let me know.
After the program's scanning of the video after being import into the program, it is very much straight forward with the key settings mentioned above.
Looking forward to your results.
Thanks.

PIP and Green screen

Is it possible to have a green screen background, and also have footage in the picture in picture? If so can some help??

Thank you for your reply. I saw this solution on another thread and tried the following. Will go into what I found.
The green screen function will only work if the movie is on top of something else. Therefore, when you save it it is saving the file with the background behind it. I tried several.
Then if you import it into your main project, it contains that background and using PIP will certainly shrink it, but again, you can't green screen it....back to step one.
This solution you reference would work if the file contained the subject against a transparent background, but it doesn't, it contains whatever you had to use under it to get the green screen to work.
Sorry if I am missing something. Two days into this and can't believe it can't be done.

Video card for HD and green screen

I use a windows XP64 based machine with a quad core I7 920 processor and 12 gigs of RAM with nVidia 260 card. I use CS3. Right now I am having severe crash issues in Premeire CS3.
I do HD 1080i video editing with up to 4 layers of green screen. I currently use Adobe AE Keylight2 for my greenscreen work. I bring the files into Premeire with "Dynamic Link". I crash, and crash, and crash. What is my best option to prevent crashing. A Quadro video card? which one? . Or, Matrox Max. My budget is somewhat limited. I can't get both. I want to upgrade to CS5 but need to fix this problem, now.
Sincere thanx to anyone who can help

I appreciate the quick answer and am considering moving to Windows
7 (64). What is the sad story about Matrox? What is the best way to speed
up my rendering or processing without having to purchase another cpu? Thanx once again for your quick response. I render primarily to h.264

Tutorial for Colour Correction and Green screen

Anyone know of any good tips to remove the green look from white hair? or any tutorials I can read for colour correction with green screen?
I filmed a getlemen who has white hair on a green screen. The colour of his hair picked up a slight tint of green and I need to remove it. Can anyone lend some sound advice.
Thanks

Your best chance is to study the manual carefully and to cycle through the chromakeying filters you have at your disposal. If you were using DV, you will probably need to purchase a far more capable keying application, one that compensates for DV's terrible chroma resolution.
The books on the shelves at Borders and Barnes/Noble for After Effects and FCP will help you get the most from your existing key filters. You will ned up stacking several copies of your footage with different key settings. Without preproduction, the proper lighting, a good camera and adequate tape format, managingr a good chromakey in post is very difficult.
google chromakey, too.

Tough one for any one.... my laptop screen is a pretty pink and green but if I connect to my TV via HDMI it works flawlessly
Thank you

You have done very good test. Graphic card is OK and troublemaker is LCD display.
On eBay you can find it pretty cheap.
Can you exchange it alone?

Flashing blue and green screen

Hi, I upgraded to Quicktime Pro 7 and now no videos, wether .mov, .avi or anything show up in the player. I get sound fine...the visual is just a flashing green and blue screen. Also, this is a product I purchased, and now I am told I can't get support from an apple technician. What kinda support is that?! I can't talk to anyone who will help me troubleshoot?
Thanks to anyone out there that can help me.

Quicktime Control Panel / Advanced tab
under Video switch to "Safe mode". Quit QuickTime and any open browser and try the file again.

HT201263 Blue and green screen

My iPad won't turn on. Held both buttons and got a blue and green lined screen. Help???

You have to hold the sleep and home buttons down at the same time for at least 10-15 seconds and the key is to wait until the Apple logo appears on the screen before you let go of the buttons. It can take even longer than 15 seconds.
But the fact that you are seeing this funky screen makes it seem like it could be a hardware problem. Anyway, you still have to go through the troubleshooting steps and see if anything will help restore the iPad to working order.
Start here. Read any and all of the links that are in the kb article as well.
